Making yellow wax ribbons, black glass paint strips, alkali-free glass ribbons for cable joints, etc. How to carry out moisture treatment before construction?

Answer:

(1) Constant temperature drying method: roll the insulating tape into a small roll with a diameter of 25~30mm, put it in a constant temperature drying oven at 110~120 °C for 4~5h, cool it out and put it into a dry sealed cylinder.

(2) Oil immersion method: put the small coil of insulation tape into the cable oil with constant temperature of 120~130 °C, keep the distance from the bottom of the pot to 30mm, after a certain time, the oil no longer produces foam and then take it out and put it into storage. In tanks with cable oil, the oil level should exceed all loaded objects and seal them.
